    How to begin?....
    My last/current CMU block wall is 14'x 10' in a 90 degree angle. 3 course (3, 8"blocks) tall.
    I'm filling each cell with quikrete and #5 re-bar, but I'm running short of quikrete.
    Can I use sand + quikrete to make up the difference, and what should be the ratio?

    Well, it's a done deal, but to answer-
    Foundation is approx. 6"D x 12"-14"W, with #4 bar
    #5 bar vert. to catch every block (not every cell)
    3 course tall (24"+grout), and all cells filled with a 21" stick of #5 bar.
    My mix ended up being 2- #80's of quikcrete with around 30-40lbs. of clean sand in the mix, just for the cells. I still had to pick up another 4 bags to get it finished.
    let me know if I'm looking at problems down the road with that mix.
    Top it off, my stone order was only 1/3rd complete, after 80mi. round trip. That's another story.
    Thanks, JB
